Abstract
In this investigation we have shown the preparation of carboxylic acid containing new chromophore : 4-(3-(4-nitrophenyl) thioureido) benzoic acid and its use.The chemical modification of chitosan, e.g., chitosan- acid salt complexes is done under mild conditions. The synthesis of chromophore was carried out by conventional methods and the novel polymer complex was soluble in most of the organic solvents. The modified chitosan was analyzed by various techniques like optical properties by UV and SHG spectroscopy which showed red shift. The antibacterial activity showed obvious effect against food pathogenic bacteria.
